Fourmile polychrome is the culminant product of the great Cibola Anasazi pottery tradition. It was made by Anasazi living in the Mogollon Rim area around AD 1400. It was not only some of the best made and best fired pottery produced in the prehistoric Southwest, it also shows some of the finest abstract design in the long and varied Southwestern pottery tradition. It was widely traded, as were previous Cibola Anasazi types. The Cibola Anasazi probably survived as the Keresan speaking Pueblo people of New Mexico.
